I install the latest nvidia drivers without problem, ive googled google untill it says i give up lol, but all im trying to do is get my monitors native resolution which is 1440x900@75

When I installed the drivers I got the menu item System > Administration > NVidia X Server Settings

Which lets me configure all sorts of Graphics settings including native resolution Have you found this option?

Good Luck

Thanx for the prompt reply , yes ive found this, but it doesnt give me my native resolution i require .....

Do you have a widescreen (1440x900) CRT monitor?

Also at this point i'd like to say that some sections of your xorg.conf file are 'duplicated'. For example you have two "Section Monitor" and two "Section Device".

#5

Adding to the above my resolution atm is 1152x864@60

Has the system correctly identified your LCD from "Detect Displays"? X Server Display Configuration My settings = Model DELL E248WFP (DFP-0 on GPU-0) GPU = GeForce 8600 GT My Resolution is set to Auto but the drop-down has 1440 x 900 Is it the refresh rate that's your issue? mine's running at 60Hz and I can't see where to change it.

Ok, but comparing this to your xorg.conf I'm assuming you also have a CRT set up as a secondary display? If not, then you need to totally reconfigure (read, wipe out) xorg to remove the duplicate listings.

I would suggest first:

sudo dpkg-reconfigure xserver-xorg

This will put xorg.conf back to it's original near-empty state. From there you should add your hsync and vrefresh ranges to the single monitor entry. Don't add anything other than that just yet. Restart X and let's see what crops up from there.

sudo /etc/init.d/gdm restart

or ctrl+alt+backspace to restart X.

Your xorg.conf contains a reference to a CRT monitor as well as a line mentioning 1152x864 (along with the duplications i mentioned above). Most lcd monitors need no resolution setting as they are given their defaults automatically. If you are comfortable backing up this file and replacing it then you could back it up and run``` sudo-dpkg reconfigure -phigh xserver-xorg

sudo nano /etc/X11/xorg.conf

EDIT - Do you have an secondary display? If so ignore the above instructions.

No it shouldn't be. From here i think you should reset your xorg.conf file to the default by opening a terminal and typing``` sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.backup

sudo dpkg-reconfigure -phigh xserver-xorg

nano /etc/X11/xorg.conf

Section "Device"
	Identifier	"Configured Video Device"
	Driver		"nvidia"

Then press Ctrl+x to save this file. Then preass Ctrl+Alt+Backspace to restart the xserver.

#14

Did what you said, and the screen went blank ...

When i restarted i was told nvidia x is not in use etc ...

OK. Then replace xorg from the command line with``` sudo cp /etc/X11/xorg.conf.backup /etc/X11/xorg.conf

#16

Done m8, everythings back to normal ...

Brucey

#17

Do ``` sudo apt-get install nvidia-xconfig

sudo nvidia-xconfig --composite --add-argb-glx-visuals

BruceyHmmm. Bugger. Sorry Bruce but i can't help very much further. Just copy the xorg.conf back again with``` sudo cp /etc/X11/xorg.conf.backup /etc/X11/xorg.conf

I know my my cheap kvm causes an issue like this for me, seems to prevent the monitor reporting its capabilities properly. I had to use displayconfig-gtk command to force the correct monitor type to get it to work, which I think just puts the relevent info into xorg.conf.

Are you on 8.04? If so you might need to

sudo apt-get install displayconfig-gtk

If you're on 8.10 displayconfig might not be an option any more, you might need to read up on the xrandr command. I'd start at this page: https://wiki.ubuntu.com/X/Config/Resolution

#25

Hi i tried to install "displayconfig-gtk" and it said ....

Package displayconfig-gtk is not available, but is referred to by another package.

btw im using ubuntu 8.10

Is there anything else i can do guys?

Cheers Brucey

Probably 75% of the display problems I've run into have been due to incorrect monitor auto-detection. The easiest way to solve this is by adding the hsync and vrefresh ranges of your particular monitor to xorg.conf. So google the specs for your monitor, or look at its documentation and find the hsync and vrefresh ranges so first

gksudo gedit /etc/X11/xorg.conf

then plug them in like so:

Section "Monitor"
	Identifier	"Configured Monitor"
**	HorizSync          30-82**
**	VertRefresh        56-76**
EndSection

Change the bold values to those of your monitor specification (you may have to add the lines themselves, but don't change the identifier line), then restart X with

sudo /etc/init.d/gdm restart

or ctrl+alt+backspace.

#27

Well guys ive sorted the problem :D

I disconnected my dual monitor switcher, then installed wubi on my duel core athlon (Along with xp for now)

I installed nvidia drivers etc ...

Checked my nvidia x server settings, and there it was 1440x900@75 ;)

So the moral of the story is dont use a monitor switcher ...

I have 1 more question in my preferences/screen resolution its reporting my refresh rate different from nvidia x server settings? altho if im right nvidia x overrides that?

So atm im having a complete ball lol, ive just installed compiz fusion, and wine, and im away to try call of duty 2/3 :D

Cheers Again
